Abstract: The text study the application of Photosynthetic Bacteria in rice potted plant, The result indicates that vary disposal have different impacts on physiology activities, growth characters and yield of rice, which have not remarkable effects on catalase and pigment, but which can increase superoxide dismutase of rice, improve the amount of bacteria, actinomyces and azotobacter of soil, add the tillering of rice, improve the yield of rice。superoxide dismutase tillering and yield of rice can improve 68.29 percent, 30.88 percent and 36.75 percent than comparison respectively. the applying methods of Photosynthetic Bacteria on rice is touching root disposal, which can increase yield of rice greatly.
